2 Figure 1 Catheter-directed thrombolysis (pulse-spray method). A: Pre-treatment venogram showing complete occlusion of the left common femoral vein and iliac vein. B: After implantation of the retrievable filter in inferior vena cava, contrast media injected through the pulse-spray catheter penetrated the obstructing thrombus. C: Brisk flow was restored in the common femoral and iliac veins after pulse-spray pharmacomechanical thrombolysis, but significant residual stenosis of the left common iliac vein was demonstrated. D: Percutaneous balloon venoplasty was done. E: A Wall stent was inserted in the left common iliac vein (arrowheads). After this procedure, the filter was retrieved successfully , RR, 0.7; 95 CI, RR, 0.5; 95 CI, RR, 1.2; 95 CI, ; RR, 1.4; 95 CI, ; 1 35 RR, 1.7; 95 CI, ; RR, 1.7; 95 CI, ; ACCP American College of Chest Physicians 14 1 Grade 2C 2 2 catheter-directed thrombolysis:cdt CDT infusion pulse-spray Fig Vol. 49, 2009

8 Thrombolytic Therapy and Inferior Vena Cava Filter Implantation for Deep Vein Thrombosis Norikazu Yamada 1 and Takeshi Nakano 2 1 Department of Cardiology, Mie University Graduate School of Medicine, Mie, Japan 2 Honorary Professor, Mie University, Mie, Japan deep vein thrombosis, thrombolytic therapy, catheter-directed thrombolysis, inferior vena cava filter, pulmonary thromboembolism Conventional treatment for deep vein thrombosis, such as heparin and warfarin, has already established, but there is an ongoing controversy if more aggressive therapy, such as thrombolytic therapy, especially catheter-directed thrombolysis, should be used in selected patients to achieve faster clot lysis and prevent the postthrombotic syndrome. The previous reports suggest that thrombolytic therapy may be efficacious in well-chosen patients. Inferior vena cava (IVC) filters can reduce short- and long-term pulmonary thromboembolism, but permanent IVC filters seem to be associated with a higher incidence of IVC thrombosis and lower-extremity deep vein thrombosis than anticoagulation alone. Recently, several non-permanent IVC filters are also available in Japan. These filters may be attractive alternative to permanent IVC filters for patients unnecessary for life-long protection, but further information is necessary before their efficacy relative to permanent IVC filters can be established. Current status and future perspectives of thrombolytic therapy and IVC filter for deep vein thrombosis are described in this chapter.
